Hello everyone im new the the thread, here my problem, i got a 2002 civic Si, yesterday i decided to install a system i put in
two 12 Inch audio Bhan Special edition subs 400 watts Each sub, with a 800 watt pioneer amp and a JVC Deck, the problem i get is my bass keeps cutting off on songs, and when i put my volume over 20 there is not bass at all with the subs, i have no idea what the problem is, im pretty sure the amp can handle the subs, so is it my gain that i should reduce? thanks for the help, t-care

 

you probably have the subs wired up wrong. What are the ohms and how do you have them wired?

 

well i got no ideaaaaaaa, i payed someone 2 do it who knew what they were doing so im pretty sure the wiring is right lol atleast i hope so

 

double check wiring, what do you mean there is no bass at higher volume?
try adding capacitor to make the bass more clear.

 

First of all, welcome to HCF.

Now, if your subs are playing and then cutting off, it sounds like your amp may be going in to "protect" mode or "clipping." Kinda like throwing the breaker in your house, only it resets itself when it's Ok to. This is almost always caused by the subs drawing too much power from the amp, or in technical terms too much (ohm) load, as Polo was referring to. If your subs are 4ohm and the guy who hooked them up ran them in "parallel" or "bridged," as almost everyone does these days, then your amp is in a 2 ohm Mono load and is probably only stable to a 2 ohm Stereo load. Does that make sense?

Check the wiring of the subs to the amp and make sure that the + and - of each speaker is running into it's own terminal and then get back to us.

 

Street Sniper is right... BUT also check for cables that are pinched to metal. Electrical systems can handle some interference. But once there is too much of it, bells and whistles go off. Your amp is going into protect mode, if you didnt have that feature, you would be going back to your audio store to get a new one.

 

ALso remember when you bridge an amplifier it sees half the ohms you put to it. So if you parallel 2 4ohm subs to 2 ohms and bridge the amp it sees 1 ohm.


Also if you turn it up and there is no bass are the subs moving and trying to make sound? If so 1 is out of phase, just revers the speaker wires on ONE of the subs.
